[intermediate relay]DZB-10B series maintains intermediate relay

2026-6-11 17:52:37

Application of DZB-10B series intermediate relay

The DZB-10B series intermediate relay has a self holding winding and is used in DC operated relay protection circuits to increase the number and capacity of contacts and improve the reliability of contact operation. DZB-11B, 12B, and 13b are intermediate relays that maintain voltage starting current; DZB-14B is an intermediate relay for maintaining current starting voltage; DZB-15B is an intermediate relay that starts with voltage or current and maintains current or voltage.

Working principle and structure of DZB-10B series intermediate relay

2.1 Relays are electromagnetic relays. When voltage or current is applied to the working winding, the armature moves towards the closed position, the dynamic contact closes, and the dynamic contact opens. After the relay is activated, the circuit of the holding winding is connected. If the working winding loses power, the relay will not release. Only when the holding winding loses power, the armature will return to its original state under the pressure of the contact piece, and the dynamic contact will open and close.
2.2 Relays have two structures:
2.2.1 Protruding plug-in structure. Adopting Aji JK-1 type shell, its outline and opening diagram are shown inAppendix IThe internal wiring of the relay is shown in Figure 1.
2.2.2 Embedded plug-in structure (with/Q in the model). Using the Xuji A11K shell, its external shape and opening diagram are shown inAppendix IIThe internal wiring of the relay is shown in Figure 2.
2.2.3 If it is necessary to change the wiring method from the back of the board to the front of the board, a front wiring socket and a middle frame should be added. SeeAppendix IIFigure 2 Embedded Internal Wiring Diagram

2026-6-11 17:51:53

purpose
The JQ-2 electromagnetic relay is used in automatic devices and communication equipment to switch circuits with DC or AC currents below 20A.

2. Action principles and structural characteristics
2.1 Action principle:
When a direct current is applied to the coil of the relay, current flows through the coil, causing the iron core to be magnetized and the dynamic spring on the armature to rotate with the rotation of the armature, ultimately causing the contact to close. When the coil is powered off, the magnetic force disappears and the armature returns to its original position due to the reaction pressure of the spring plate.
2.2 Structural Features
This relay is an electromagnetic relay, and the power supply to the coil is direct current. Its components are the iron core, yoke plate, armature, coil, and contact system. The top of the yoke plate has an angular blade, but the armature rotates flexibly on the blade. The center of the armature is equipped with an adjustable magnetic isolation pin, which can adjust the suction and release time when necessary.

Application of DZ-100 series intermediate relay

This relay is used in various automation circuits to expand the controlled circuit. The power supply for circuits using this relay is direct current, with a voltage not exceeding 110V.

2. Action principle and structural characteristics
2.1 Action principle
When a direct current voltage is applied to the coil of the relay, current flows through the coil, magnetizing the iron core and attracting the moving piece. The contact piece is pushed by the other end of the passive piece, causing the moving contact to close and the moving contact to open.
When the coil loses power, the magnetic force disappears and the moving piece returns to its original position under the pressure of the contact system.
2.2 Structural Features
This relay is an electromagnetic fast acting intermediate relay, consisting of four parts: iron core, yoke plate, rotor, coil, and contact system.
The relay adopts a plug-in structure, and there are leaf springs inside the socket to ensure reliable contact. When in use, the relay is inserted into the socket. In order to prevent the relay from sliding out of the socket due to vibration, a spring ring is installed between the relay and the socket. If it is fixedly installed, the socket can be omitted and the wiring can be directly welded to the base plate of the relay.
The relay has a transparent plastic casing for observing its operation.
The internal connection of the relay is shown in Figure 1.

Application of DZK-100 series intermediate relay
This relay is used in various protection and automatic control circuits for DC operation to expand the control range.

Meaning of Model 2

Overview of the Structure of DZK-100 Series Intermediate Relays
The DZK-100 series relay has a mountain type snap on electromagnetic mechanism, and the internal wiring of the relay is shown in Figure 1.

Figure 1 Internal wiring diagram of DZK-100 series relay
According to this, DZK-111, DZK-114, DZK-121
DZK-124 DZK-134 DZK-141 DZK-144

The intermediate relay in this series features a mountain shaped snap on electromagnetic mechanism, with the coil located on the center pillar. The relay consists of five parts: a mountain shaped iron core, coil, armature, bracket, and contact system.
In order to reduce the power consumption and temperature rise of the relay, additional resistors are added in series in the relay voltage winding circuit.
When the coil of the relay is energized, current flows through the coil, causing the iron core to magnetize and attract the armature. When the coil is de energized, the magnetic force disappears and the armature is released. The movement of the armature drives the support plate of the spring, causing the spring contacts to be attracted and disconnected accordingly.

Application of DZ-500T series intermediate relay
The DZ-500T series intermediate relay (hereinafter referred to as the relay) is used in DC to 220V protection and automatic control circuits to expand the control range and improve contact capability.

Structure and principle of DZ-500T series intermediate relay
The action of a relay is generated based on electromagnetic principles. A relay is composed of iron heart plates, coils, and contacts. When a direct current voltage is applied to the relay coil, current flows through the coil, causing the iron core to magnetize and attract the moving piece. The contact spring is pushed by the passive piece, causing the moving contact to close and the moving contact to disconnect. When the coil is powered off, the magnetic force disappears, and the moving piece returns to its original position under the pressure of the restoring spring and the contact system.
2.2 The relay adopts a protruding installation main body part installed in a plug-in structure housing, and the relay contact system is installed upward on a vertical screen.
The internal wiring diagram of the relay is shown in Figure 1.
2.4 The external dimensions and installation dimensions of the relay are shown in Figure 2.

1 Purpose

DZ-10, DZ-15, DZ-16 series intermediate relays are used as auxiliary relays in various protection circuits to increase the number or capacity of contacts of the main protection relay.

Overview of Structure 2
This series of relays is an electromagnetic pull in instantaneous action relay.
The "mountain" shaped magnetic conductor is composed of a magnetic yoke plate and a cylindrical iron core, with a coil mounted on the iron core. The flat armature is hinged with a bronze thin bent plate and a magnetic yoke plate.
The dynamic and static contact systems are respectively fixed on the armature and magnetic yoke. When voltage is applied to both ends of the coil, the armature moves towards the suction position and changes the contact state of the contacts (such as closing the dynamic contact). After removing the voltage (or reducing the voltage to the return voltage), the armature returns to its original position under the reaction force of the tension spring and contact piece, and the contact returns to its normal state (such as closing the dynamic breaking contact).
The DZ-15 intermediate relay has two sets of dynamic contacts and two sets of dynamic contacts.
The DZ-16 intermediate relay has three sets of movable contacts and one set of movable contacts.
The DZ-17 intermediate relay has four sets of dynamic contact points.
The relay is suitable for wiring in front of or behind the board. The internal wiring of the relay is shown in Figure 1:
